我正在尝试用装饰器构建JS反应项目.我的.babelrc看起来像这样:
{
"presets": [
"@babel/preset-env",
"@babel/preset-react",
],
"plugins": [
"@babel/plugin-transform-runtime",
"@babel/plugin-transform-object-assign",
[
"@babel/plugin-proposal-decorators",
{
"legacy": true
}
],
["@babel/plugin-proposal-class-properties", { "loose": true }]
]
}
添加@ babel / plugin-proposal-decorators问题再次出现.
我正在使用babel 7,webpack 4并做出反应16.5
webpack.config.js:
const path = require("path");
const webpack = require("webpack");
const componentName = "reports-desktop";
const publicFolderRelativePath = "../../../../../../public/js";
const ignorePlugin = new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/);
module.exports = {
entry: './reports-desktop.js'
,
output: {
path: path.resolve(__dirname, publicFolderRelativePath),
filename: `${componentName}.js`
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
}
]
},
plugins: [
ignorePlugin
]
};
的package.json:
{
"name": "captain",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"watch": "webpack -w --mode development --progress --color --display-error-details",
"build": "webpack --mode production"
},
"keywords": [],

}
}
我可能使用@ babel / plugin-proposal-decorators错了吗?正如它在文档中所说,这应该解决我的问题,但它仍然出现.
解决方法:
我遇到了同样的问题,但我能够通过运行npm install –save-dev @ babel / plugin-proposal-decorators并添加[“@ babel / plugin-proposal-decorators”,{“legacy”: true}]到我的.babelrc中的插件部分.
对我来说.babelrc的插件部分现在看起来像这样:
"plugins": [
["@babel/plugin-proposal-decorators", { "legacy": true }]
]
